自我觉醒，在睡觉前决定的指定时间醒来，可以防止血液循环系统的衰竭，如心脏病发作，心率或血压在清醒时急剧增加。先前的研究表明，通过年轻参与者的自我觉醒，在短暂的午睡醒来之前，心率发生了预期的变化。然而，自我觉醒对老年人的影响仍不清楚。本研究探讨了老年人午睡（20分钟）时自我觉醒对心率和血压的影响。9名参与者[74.1（SD = 5.01）岁]同时经历了自我觉醒和强迫觉醒。在自我觉醒条件下，发现血压在预定的觉醒时间之前逐渐升高，并且心率在觉醒时没有显示出快速增加。相比之下，强迫唤醒引起心率和血压的急剧增加。这些结果表明，自我觉醒有利于更平稳的过渡，从睡眠到清醒，通过自主激活的时间之前的自我觉醒。
Self-awakening, waking up at a designated time decided before sleeping, could prevent failure in the blood circulation vessel system such as heart attack, acute increases in heart rate or blood pressure upon waking. Previous research showed that anticipatory changes occurred in heart rate prior to awakening from a short nap by means of self-awakening for young participants. However, the effects of self-awakening remained unclear for elderly people. The present study examined the effects of self-awakening on heart rate and blood pressure in a short afternoon nap (20 min) among the elderly. Nine participants [74.1 (SD = 5.01) years old] underwent both self-awakening and forced-awakening conditions. In the self-awakening condition, it was revealed that blood pressure gradually increased before the scheduled time of awakening, and that heart rate did not show a rapid increase at arousal. In contrast, forced-awakening induced acute increases in both heart rate and blood pressure. These results suggest that self-awakening facilitates a more smooth transition from sleep to wakefulness via autonomic activation before the time of self-awakening.
